| Abstract: | To analyze the virulence genes distribution of Listeria monocytogenes(L.monocytogenes, LM) isolated from commercial duck wings in Luoyang. 8 virulence genes (inlA, inlB, virR, mprF, dltA, dltB, dltC, dltD) from 11 LM isolated strains were detected using PCR method. The results showed that there existed 3 isolated strains with virulence gene-deleted. Detected ratioes for dltA, dltC and mprF were 90.9% (10/11), 81.8% (9/11) and 81.8% (9/11),respectively. The data indicated that these virulence genes were common for LM isolated from commercial duck wings in Luoyang, and some measures were taken to strengthen the surveillance of LM for the potential threat to commercial duck wings safety. |
